The quick and easy solution would be to get an account on a web-hotel. On
most of those you will not only get web pages but also a domain with email
accounts and email forwarders.

Yes, it is also possible to run your own server with DNS pointing to your
server for both web and mail, but especially as you don't even have a
fixed IP address I would prefer to put those services on a web hotell.

There might be a comment in sendmail.cf to not edit that file, but it is
possible to edit it anyway. I have been editing that file a few times,
usually to set a smart relay or change some timeout values. However, I
have only configured sendmail for internal networks or sending smtp only,
I have never configured sendmail to accept email from internet. If you
mess that up your server might end up as an open relay flooding the rest
of internet with spam.

The PHB wants mail that's addressed to [email]jivy@abiengr.com[/email] to show up on
our server, rather than redirecting it to his AOL account.

Would this "web-hotel" make it look like we have a real mail server
here, on the box where we have our website?

Thanks,
Rich

You'll loose your changes whenever you need to update the sendmail.cf
file after a sendmail update.

So far I haven't seen any such problem. This is from a Slackware 9.1
machine:

ls -al /etc/mail/sendmail.cf*
-rw-r--r-- 1 root root 57489 Sep 17 2003 /etc/mail/sendmail.cf
-rw-r--r-- 1 root root 60165 Jun 15 2006 /etc/mail/sendmail.cf.new

Usually when a package is upgraded in Slackware the configuration file is
not overwritten, but a new updated configuration file has the extension
..new.

You will also most likely place your website on the web hotel. So yes, you
will get a real mail server running where you have your website. It will
look more professional than having a servers on dynamic IP addresses at
some ISP. Most web hotels have functionality to redirect email to other
email accounts like and AOL account, but also the possibility to fetch
email from a pop3 account at the web hotel. Most web hotels also have a
web client for email so you can use a web browser to read and write email.

I usually prefer to use fetchmail to get my emails by pop3 from web
hotels. Then I configure sendmail for outgoing emails only. Sendmail is on
running on my internal network and is protected by firewalls so it is not
possible to connect to my sendmail from internet.
